Default [Q] restore ta with broken screen no root?

Dear xda

I need my phone to be repaired, they will not repair it is i have mij BU unlocked.


Today while in the Phonehouse (while waiting on my buddy with i-phone troubles) my xZ1 dropt, screen down on the floor.
Screen was cracked, from the right to left (down and up).
Screen is not responsing.
I have my ta bakup, and a copie of the orriginal softwhare it had when i made the backup.
I flashed stock FW only to discover/remember i have to give root rights to restore TA. I cant even unlock my screen.
does someone know a solution?

The only thing I can think of is flash kernel (like doomlord) and then restore an cwm back-up from someone with the given rootrights (for ADB I supose?) and usb-debugging on.
Will this work?
If Yes...
Is someone willing to sent me a back-up? ( is wich I can restore TA and then restore clean .534)

Please Help
